Description
Brand: YIOVVOM
How to use:
1. Press the button in a short time (1 second) so that "in" LED lighted, the voltmeter shows the value of input voltage.
2. Press the button in a short time (1 second) again so that "out" LED lighted, the voltmeter shows the value of output voltage.
3. Rotate the top screw of potentiometer clockwise to boost the value of the output voltage, anti-clockwise to reduce it.
4. Long press the button between 1 and 4 seconds to turn off the voltmeter.
How to adjust accuracy of input/output voltage: (for the person who need a highly accurate value of number)
1. Long press the button for more than 4 seconds, then release, voltmeter and "in" LED flash in synchronization entering into the input voltage calibration mode.
2. Press the button in a short time (1 second) to adjust the value (range from -0.5 - 0.5V), positive means to rises units, negative means to minus units. (Due to a unit is less than 0.1V, so you have to continuously press 1 to 5 times to see the voltmeter change 0.1V).
3. Long press the button for more than 2 seconds and then release to enter the output voltage calibration mode.
4. After calibration, long press the button for more than 2 seconds all parameters will be saved automatically and back to the voltage display.
• Input: The LM2596S Input voltage range is DC 3 V to 40 V (input voltage must be 1.5 V higher than the output voltage, no boost)
• Output: The LM2596S output voltage range is DC 1.5 V to 35 V voltage is continuously adjustable, maximum output current is 3 A
• Connect to power source, adjust the swirl button on the blue potentiometer and monitor voltage with multimeter to get the needed voltage ,boost clockwise and boost counterclockwise.(The factory default setting is 18V. Before the voltage starts to drop, you need to rotate in the reverse direction for about 15-20revolutions, 1 revolution means +/- 1V)
• Features: The buck converter consists of a 36u thick circuit board with high Q inductors with high power output LED indicators, suitable for various electronic projects.
• You can get 10 pieces LM2596S DC-DC Buck module
Power/Wattage: LM2596S
